I'm sure when you have gone out running or in your car, you have seen cyclists on the road with no lights whatsoever. I find this extremely frustrating, so I'm here to tell you: get a bicycle headlight today.
Some bikers tend to just put on reflective clothing and lights on their body if they will be biking at night, but still having a headlight is extremely important. They come separately from the bike, so a lot of people don't even know to buy them when they first start out. Also, it's illegal to ride your bike on a public street without lights at night.
